No. 814,857Claims priority, application Germany May 29, 1958 Claims. (Cl. 283-63)The invention relates to a pack of blank forms in particular however toa pack formed of a plurality of superimposed sets of blank forms.

It is known to combine a plurality of blank form sets, each setcomprising several sheets of paper, to a pack. These known packscomprise a carrier or back sheet which is folded in a zigzag fashion oneset of blank forms being fastened to each fold. In this way each set ofblank forms, while all of them are being held together by the backsheet, may be displaced relative to the next one in a shingle like wayabout the double folding length thus providing a free zone on theunfolded blank form sets for comparison, and in the same way they may bepushed back again to form a pack or book of mating blank form sets. Thenumber of pages or sheets belonging to each blank form set may be freelyselected. It is also possible for copying to use the reverse side of asheet provided with a carbon layer instead of separate carbon sheets.

The thus obtained advantage of providing packs of blank form sets whichmay be spread apart is opposed by the disadvantage that the manufactureof these packs is rather intricate and expensive so that in many casestheir use is out of the question because of the high price. Another factwhich often proves to be a shortcoming is, that the back of the foldedpack of blank form sets is substantially thicker within the foldedrange, which hinders the storing and piling possibilities of such packsof blank form sets.

According to the invention a pack of blank form sets is provided whichmay be manufactured using extremely little material and with a minimumof time and labour and which, within the range of its back is but littlethicker and thus may easily be stored and piled.

One object of the invention is to provide a pack of blank form sets inwhich each blank form set comprises a main sheet folded along one edgeto form an upper and a lower sheet and in which the backside of thelower sheet is glued to the front side of the upper sheet of the nextlower main sheet along an area which is parallel to and spaced from saidfolding edge thus forming a continuous connection between all of theblank forms sets in a zigzag fashion to accommodate a spaceddisplacement of the blank form sets relative to one another, thedistance between the glued area and the folding edge corresponding tohalf of the required width to which the blank form sets are to bedisplaced.

Another object of the invention is to provide a pack of blank form setsin which a separating or tearing line is formed by perforations or anyother suitable means being arranged on one or both of the sheets formedby the main sheet along the edge of the glued area adjacent to thefolding edge.

Another object of the invention is to provide a pack of blank form setsin which at least one subsidiary or additional copy sheet being placedbetween each of the upper and the lower sheet of said main sheets beingconnected to said main sheets by means of an adhering area arrangedparallel to and spaced from said folding edge of the main sheet.

Another object of the invention is to provide a pack of blank form setsin which at least two subsidiary or copy sheets are connected by afolding edge being placed between each of the upper and lower sheet ofsaid main sheets, the lower sheets of said subsidiary and said mainsheet of each set being interconnected by an adhering area arrangedparallel to and spaced from said folding edge of said subsidiary sheets.

Another object of the invention is to provide a pack of blank form setsin which the adhering area is arranged matingly above the adheringregion between two adjacent main sheets, the distance from the foldingedge of the subsidiary sheets being less than the distance from thefolding edge of the main sheets to the respective adhering regions.

Another object of the invention is to provide a pack of blank form setsin which at least one subsidiary or additional copy sheet between eachof the upper and the lower sheet of said main sheets being integrallyconnected to said subsidiary sheet by an outer folding edge and endingadjacent the adhering region.

Another object of the invention is to provide a pack of blank form setsin which provision is made for a line of apertures arranged parallel toand spaced from the tearing line of said main sheet, said line ofapertures coinciding with the border region of said subsidiary sheetafter being folded over, said line of apertures forming an adheringregion between said main sheets of two adjacent blank form sets and thesubsidiary sheet.

The invention proper may be employed for numerous fields of application,for instance also for the manufacture of cash receipt packs. The packmade in accordance with the invention may also be used as an endless setof forms for writing work in a booking machine, or a booking apparatus.

Further improvements and suitable developments of the invention areillustrated in more detail with the aid of the attached drawings.

In the drawings:

FIG. 1 is a perspective view of a pack of blank form sets made inaccordance with the invention when pushed together, composed of doublemain sheets, the individual blank form sets are slightly pulled apart,in order to better illustrate the construction of the pack of blank formsets,

FIG. 2 is a perspective view on the pack of the blank form setsaccording to FIG. 1, partially unfolded,

FIG. 3 is a perspective view similar to FIG. 1, however with asubsidiary sheet placed between the two main sheets of each blank formset, the subsidiary sheet being shown by way of example to be a doublefolded subsidiary sheet,

FIG. 4 is a perspective view similar to FIG. 2 of the embodimentaccording to FIG. 3,

FIGS. 5 and 6 are perspective views of a pack of blank form sets, havingone double main sheet and two subsidiary sheets, each set of blank formsconsisting of three leaves,

FIGS. 7 and 8 are perspective views of a pack of blank form sets,wherein each set of forms consists of an original sheet and three copysheets,

FIG. 9 shows a main sheet prepared for use with a further embodiment notyet folded, and

FIG. 10 is a sectional, elevational, view of a plurality ofinterconnected folded form sets of the embodiment of FIG. 9.

'l'he embodiment according to FIGS. 1 to 2 comprises a plurality ofdouble main sheets 1a, 1b, 1c, 1d, 1e, 1] etc. These double main sheetsshow a folding edge 2, by which an upper sheet 3 and a lower sheet 4 areformed. Between the upper sheet 3 and the lower sheet 4, a carbon paperis placed in a manner not shown. Instead of this, the backside of theupper sheet 3 may also be provided with a carbon layer. The back side ofthe lower sheet 4 of each double main sheet is connected along anadhering area 5 to the front side of the upper sheet 3 of the next lowerdouble main sheet. Along the edge 6 of the adhering area 5 adjacent tothe folding edge 2 the lower sheet 4 is provided with a separating ortearing line,

. 7 of the upper sheet 3 is likewise provided with perforations or thelike. The distance 'a between the edge 6 of the lower sheet 4 of thedouble main sheet from the folding edge 2 equals the distance betweenthe edge of the adhesive area 7' of the upper sheet 3 of the main doublesheet from the folding edge 2. These two distances together are equal tothe amount c, about which each set of blank for-ms may be displaced fromits adjacent set of blank forms. In the example of embodiment, the packof blank form sets is adapted to be used for accounting in a dairy,wherein in the column the volume delivered as well as the amount ofmoney become visible when the blank form sets are displaced relativeeach other.

In the embodiment according to FIGS. 3 and 4 the same reference numeralsare used as for the embodiment in the FIGURES -l to 2. The structure andthe arrangement of the double main sheets 1a etc. and the connection ofthese double main sheets differs in no way from that according to FIGS.1 to 2. In the embodiment according to FIGS. 3 to 4, however, subsidiarydouble sheet-s 8a, 8b, 8c etc. are additionally insented between theindividual main sheets 1a, 112 etc., the subsidiary double sheets beingfolded along a folding edge 9 in such a manner that two sheets '10 and11 are formed, namely an upper sheet 10 and a lower sheet v11. Thesubsidiary double sheet 8a being placed between the folds of the doublebase sheet 1a, the subsidiary double sheet 8b between the folds of thedouble base sheet 1b etc. The back side of the lower sheet 11 of eachsubsidiary double sheet 8a is then connected along an adhering strips 12with the upper side of the lower sheet 4 of the pertaining double mainsheet, i.e. the adhering stripe 12 preferably coincides with theadhering stripe '5. In this way, according to the embodiment shown inFIGS. 3 to '4, each set of blank forms comprises a unit of four sheetsto. one original sheet and three copy sheets. Also here the first set ofa new pack of form sets comprises five sheets, instead of four whenpulled apart which, however, for the reasons mentioned above does notexclude the fact that at the end of using the pack of blank form sets, acopy of each blank form set appears sidewards when the pack is pulledapart and may be summed up with the values of the other copies. Asalready mentioned, single subsidiary sheets may be provided instead ofthe double ones.

According to FIGS. 5 and 6, the main sheet is designed as a threefoldmain sheet. The upper or original sheet is connected to the first copysheet 103 along a folding edge 104, while the copy sheet 102 and thecopy sheet [103 are interconnected along a folding edge 105. The copysheet 103 is inwardly folded along the folding edge 105. As describedalready the back side of the copy sheet 102 is connected to the frontside of the original sheet 101. The distance a on the copying sheet 102which equals the space between the folding edge 104 and the outer edgeof the adhering stripe 106, again equals 7 the distance b whichcorresponds to the distance between the outer edge of the adheringstripe and the folding edge 104 on the original sheet 101. The sum ofthese distances a and b incorporates the amount about which each of theblank form sets may be transversely displaced. The copying sheet 102 maybe separated along its perforated edge I107 which correspondsapproximately to the inside edge of the adhering stripe 106. In acorresponding manner, the original sheet '101 may be separated along aperforated edge 108 which in folded condition matches the perforatededge 107. The width of the copying sheet 103 is selected to be such thatin folded condition, it does not project beyond the perforated edge 107.V

In the embodiment according to FIGS. 7 and 8, the main sheets aredesignated with 109, the reference numerals inthe individual blank formsets of the pack differing only by the addition of the letters a, b, c,d etc.

4 Each set of blank forms is provided with three copy sheets 110, 111,112. Each main sheet with the pertaining copy sheets 110, 111, 112 ismade by correspondingly folding the base sheet. While the embodimentshown in FIGS. 5 5 and 6 is provided with two copy sheets wherein thesecond copy sheet has been folded to the first copy sheet, this isaccomplished according to the embodiment shown in FIGS. 7 and 8 byfolding the main sheet so as to form the copy sheets. The original orupper sheet is connected 1() to the first copy sheet 110 by means of afolding edge 113 which is provided with a perforation. The first copysheet 110 is connected to the second copy sheet 111 by means of afolding edge 114 which is likewise provided with a perforation. Theoutside edge 115 of the second copy sheet 111 is just as free as theoutside edge of the third copy sheet 116. These outside edges 115 and116 constitute the edges of the main sheet from which the original 109and the copy sheets 110, 111 and '112 are made by folding andperforating. The back side of the third copy sheet 112 is againconnected with the front side of the original sheet 109a of the nextlower blank form set along an adhering stripe '117.

Each original sheet 109 is connected with the third copy sheet 112 by afolding edge 118, which lies in the back of the pack of blank form setsand is provided with a perforation. In a corresponding manner, also thefolding edge 114 with its perforation connecting the first copy sheet110 to the second copy sheet 111, lies along the back of the blank formset. When making the individual blank form sets, the folding edges andperforations 114, 118 may be made in one working step, in such a waythat the elevations resulting from the perforation of the folding edge114 engage the holes of the perforation 118, and in this manner thefirst copy sheet 110 and the second 3 copy sheet 111 are kept at thefolding and perforation edges 118, so that the original sheet 109 andthe three copy sheets '110, 111, 112 are safely kept along theperforation and folding edge 118. The distance a on the third copy sheet112, between the outside edge of the adhering stripe 117 and the foldingand perforation edge 118, and the distance b on the original sheet 9a,between the outside edge of the adhering stripe 117 and the folding andperforation edge 118a, are the same. Both distances together amountagain to the amount about which each blank form set may be displacedtransversely to one another. The third copy sheet 112, which isconnected with the main sheet of the next lower set of blank forms bythe adhering stripe 117, is provided with a perforated edge 119 whichextends approximately along the inside edge of the adhering stripe 117.In a corresponding manner, the original sheet 109 is provided with aperforated edge 120, which is mating the perforated edge 119 when theblank form set and the pack of blank form sets are in their superimposedposition.

The first copy sheet 110 comprises a perforated edge 121, and the secondcopy sheet is provided with a perforated edge 122. All the perforatededges 119, :120, 121

and 122 are aligned one above the other when the pack of form sets isfolded together.

0 The embodiment shown in FIGS. 9 and 10 comprises one main sheetconsisting of the original or upper sheet 201, the first copy sheet 202and the second copy sheet 203. The original sheet 201 is connected andfolded together with the sheet 203 for the second copy forming 5 afolding edge 204 which is perforated or grooved. At a desired distancefrom the folding edge 204, tear-01f perforations 205 and 206 arearranged in the original sheet 201 and in the copy sheet 203. Beside theperforation 205 of the original 201, a line of apertures 207 isprovided, adjacent to which a line of perforations 208 is arranged. a

The sheet 202 forming the first copy is connected and folded to thesheet 203 for the second copy, forming the folding edge 209. At the freemargin, the sheet 202 is perforated along a line 210 in a width beingslightly may greater than the line of apertures 207 of the sheet 201.

The set of blank forms is made in the following manner: The sheet 202 isfolded inwardly along the folding edge 209, so that the edge 211 of thesheet 202 coincides with the perforation 206 of the sheet 203. Thereuponthe sheet 201 is folded about the folding edge 204 onto the sheet 202,so that now the sequence of the sheets is 201, 202, 203. By placing thesheets one upon the other in this manner, the line of apertures 207 lieson the edge portion 213 of the sheet 202. By applying a stripe of gluealong the line of apertures 207, the glue comes in contact with theportion 213 of the sheet 202. A similarly prepared main sheet set is nowplaced on this set, whereby as a result of the stripe of glue the firstset of forms is connected to the second set of forms, namely in such amanner that the edge portion 213 of the sheet 202 of the bottom set isconnected to the bottom side of the sheet 203 of the top set. Theindividual blank form sets are cut at the right hand side at edge 209 asshown in FIG. 10, so that open sets of blank forms are obtained, bywhich the insertion of the carbon paper is substantially faciliated.
